Abstract

　入射光量や気温・体温や指の置き方が変化しても高精度の認証を可能とする。 　指に赤外光を照射する光源と、透過光によって撮像し、画像信号を出力する撮像手段８と、画像信号から低周波輝度成分信号を抽出する低周波輝度成分抽出手段６１と、画像信号から中周波輝度成分信号を抽出する中周波輝度成分抽出手段６２と、低周波輝度成分信号を用いて中周波輝度成分信号を補正する補正手段６３と、補正された中周波輝度成分信号を４値の分布が所定の比率になるように４値化する４値化手段６４と、４値化された４値化画像を記憶しておく記憶手段７と、４値化された評価対象となる評価４値化画像と、記憶手段に予め記憶されている登録４値化画像との相関係数を、正規化相関法によるパターンマッチング方式を用いて算出する相関係数算出手段６５と、相関係数に基づいて、評価４値化画像と登録４値化画像とが同じ指を撮像して得られた画像か否かを判断する判断手段６６と、を備える。
